Marta_Voda [28]3 years ago
4 0

Answer:

  1 unit = 557 miles

Step-by-step explanation:

The scale shows that 1 unit corresponds to 557 miles. Since we don't know the length of 1 unit, the best we can say is that the scale is ...

  1 unit : 557 miles

or

  (1 unit)/(557 miles)

What is the width of a rug that is 36 1/4 square feet and 8 3/4 wide
blondinia [14]

Answer: 4\frac{1}{7} ft

<u>Step-by-step explanation:</u>

Area (A): 36\frac{1}{4} = \frac{4(36)+1}{4} = \frac{144+1}{4} = \frac{145}{4}

Length (L): 8\frac{3}{4} = \frac{4(8)+3}{4} = \frac{32+3}{4} = \frac{35}{4}

width (w): W

A = L x W

\frac{145}{4} = \frac{35}{4} x W

(\frac{4}{35})\frac{145}{4} = (\frac{4}{35})\frac{35}{4} x W

\frac{4(145)}{35(4)} = \frac{145}{35} = \frac{5(29)}{5(7)} = \frac{29}{7} = W

\frac{29}{7} = \frac{7(4) + 1}{7} = 4\frac{1}{7}

You ask a neighbor to water a sickly plant while you are on vacation. Without water the plant will die with probability 0.7. Wit
Lina20 [59]

Answer:

0.2416

Step-by-step explanation:

P(forgot to water | dead) = P(forgot and dead) / P(dead)  

->With water it will die with probability 0.45

P(watered and dead) =0.83 x 0.45 = 0.3735

->Without water the plant will die with probability 0.7

P(forgot and dead) = (1-0.83) x 0.7 => 0.17 x 0.7 =>0.119

P(dead) =  P(watered and dead) +P(forgot and dead)

P(dead) = 0.3735 + 0.119= 0.4925

P(forgot to water | dead) =0.119 / 0.4925= 0.2416

Therefore, the probability the neighbor forgot to water the plant is 0.2416
